Pitbulls are pregnant for about 58 to 68 days, which is roughly two months. This is a relatively short gestation period compared to other breeds.
During this time, the dam's body will undergo significant changes to accommodate the growing puppies. Her belly will expand, and she may experience weight gain, especially in the last few weeks.
Pitbulls typically give birth to 1 to 8 puppies per litter, but the average litter size is around 5 to 6 puppies.

Pregnancy Signs and Detection
Determining whether a Pitbull is pregnant can be a bit tricky, but there are some telltale signs to look out for. Physical changes typically don't become evident until the second half of pregnancy.
Your veterinarian has a few tools at their disposal to determine whether your Pitbull is pregnant, including hormone tests, palpation, X-rays, and ultrasounds. These tests can be used to confirm pregnancy, but it's essential to schedule a vet appointment around three to four weeks into pregnancy.

A pregnant Pitbull may experience nausea, gastrointestinal upset, and appetite loss around three weeks into pregnancy, similar to morning sickness in humans. This should only last a week or so.
Signs of pregnancy in Pitbulls can be subtle, but they do exist. Around day 40 of pregnancy, the belly will begin to noticeably expand, continuing to do so for around three weeks. The nipples will also enlarge and in the final week of pregnancy, they may leak milk.
Here are some common signs of dog pregnancy to look out for:
- Abdominal swelling: This is one of the most noticeable signs of dog pregnancy, but it's not the only one.
- Behavior changes: Your Pitbull may become lazier or more affectionate than usual.
- Appetite shifts: Your dog may experience a quick phase of morning sickness, which can cause appetite changes.
- Vomiting: Morning sickness can also cause mild vomiting.
- Weight gain: Your Pitbull will gain weight, primarily around the abdomen, as the pregnancy progresses.
- Nipple changes: Around five to six weeks of pregnancy, your Pitbull's nipples may become larger, darker, and more prominent.
- More urination: Your dog may drink more water and pee more frequently.
- Nesting behavior: In the later stages of pregnancy, your Pitbull may exhibit nesting behavior, such as rearranging bedding or searching for a quiet, comfortable place to give birth.
- Visible puppy movements: As your dog's due date approaches, you may be able to see the puppies moving around in your dog's abdomen.
Gestation Period and Stages
The gestation period of a Pitbull dog is approximately 63 days from conception, but this can vary by several days. This short gestation period is relatively quick compared to humans, lasting about 9 weeks total.
To determine the length of pregnancy, hormone measurements are often used. These measurements can be taken through vaginal smears and blood tests to monitor reproductive hormones during the breeding process. This helps breeders determine the best time to breed their Pitbull, as well as the length of gestation and the potential due date.
Here's a breakdown of the gestation period according to accurate hormone measurements:
- 56-58 days from the first day of diestrus
- 64-66 days from the initial rise in progesterone
- 58-72 days from the first time the bitch allowed breeding
Gestation Period
The gestation period in dogs is a crucial aspect of their pregnancy. It's approximately 63 days from conception, but this can vary by several days.
Sperm can live for several days inside the female, making it hard to predict the length of pregnancy without a veterinarian's assistance. Hormone measurements, however, give a much more exact time frame for gestation.
Here's a breakdown of the gestation length according to accurate hormone measurements:
Pregnancy in dogs is relatively short, lasting about 9 weeks total, and each day matters.
Month Two
Month Two is a time of rapid development for the puppies. By day 32, eyelids have formed, and by day 35, toes are visible.
The claws start to form around day 40, followed by the coat and skeleton a few days later. By day 50, an x-ray can reveal the number of puppies in the litter.
A noticeable increase in appetite is one of the first signs of pregnancy in the bitch. Weight gain of 20-to-50 percent is also common during this time.
Increased urination and behavioral changes are other signs of pregnancy. Clear, odorless vaginal discharge is also a sign, as is an enlarged, firm abdomen starting around day 45.
Visible puppy movement in the abdomen can be seen around day 50, and decreased appetite may occur around the same time.
Labor and Whelping
The gestation period for a Pitbull can last anywhere from 58 to 68 days, but the labor itself can be a bit unpredictable.
On average, the active stage of dog labor lasts 6-12 hours. However, just as is the case for humans, labor can be shorter or longer. You can expect your Pitbull to start showing signs of labor about a week before the due date, such as eating more and gaining weight.
The dogs' labor may last from 12 to even 60 hours, so it's essential to prepare for it in advance. To help you get ready, here are some essential items you'll need:
- Sterile gloves;
- Sterilized scissors; and
- A bottle with prepared formula.
During stage two of labor, puppies are delivered, and this stage can take anywhere from 1-to-24 hours. Each delivery should not last more than 1-to-2 hours, and normally occurs every 30-to-60 minutes.

How Long is Labor?
Labor is a crucial and often nerve-wracking experience for dog owners.
The active stage of dog labor can last anywhere from 6 to 12 hours, but it's essential to remember that labor can be shorter or longer.
Knowing the total number of expected puppies can be helpful in determining when your dog is finished with stage two. This stage can take anywhere from 1 to 24 hours, with each delivery lasting no more than 1 to 2 hours and occurring every 30 to 60 minutes.
The dogs' labor may last from 12 to even 60 hours, so it's crucial to be prepared and have a plan in place.

Preparing for Whelping
As you approach the final weeks of your dog's gestation period, it's essential to prepare for whelping, also known as labor or birthing. You can expect your dog to give birth within a relatively short period of time, typically two to three months after conception.
Dogs pass through the stages of pregnancy quickly, so it's crucial to be prepared for whelping. This means having all the necessary supplies and a plan in place to ensure a safe and healthy delivery for both the mother and the puppies.
The gestation period in dogs is indeed short, which can be both exciting and nerve-wracking for new dog owners. By being prepared, you can help minimize stress and ensure a smooth whelping process.
Calculating and Determining Pregnancy
A dog pregnancy can be challenging to determine, but there are ways to figure out if your pitbull is pregnant.
Gestation in dogs lasts for about 63 days, give or take a few days, ranging from 58 to 68 days. This period can vary, so it's essential to keep track of the exact date of mating.
To confirm pregnancy, veterinarians use four methods: hormone tests, palpation, X-rays, and ultrasound. These tests are time-sensitive, so it's crucial to provide your vet with the mating date or an estimate.
If you know the mating date, a palpation test can be performed 28 days after breeding to confirm pregnancy.
Here are the key milestones in determining pregnancy:
- 21-30 days after conception: Blood test for relaxin hormone
- 21-30 days: Abdominal ultrasound or physical exam to confirm fetuses
- 24-35 days: Palpation (manual examination by touch) to confirm fetuses
- 43-45 days: X-rays to detect fetal skeletons
- 50+ days: X-rays to determine litter size
Keep in mind that more than 70 percent of fetal growth occurs after the first five weeks of pregnancy, and you may not notice significant weight gain before week five.
To calculate the due date, simply add 63 days to the date of mating.
